Oral Turinabol, or 4-chlorodehydromethyltestosterone (often called "OT" or T-bol by athletes) was the most widely used drug for the East German Olympic Doping Program, known as "State Plan 14.25." It was given to roughly ten thousand athletes whose results were meticulously recorded by scientists, coaches, and doctors working for the East German Olympic program. As a result of this, it is one of the most extensively researched Anabolic/Androgenic Steroids ever produced, with regards to it's effects on strength, speed, and athletic training.
